Zen browser "Add to Firefox" button not behaving correctly

[TyceHerrman]

Using the newest version of Zen Browser as of issue creation (1.0.2-b.2) and was experiencing same issue on previous versions of Zen Browser. Using an M1 macbook air.

When I click the add to firefox button, four black circles appear but nothing else happens.

Tried disabling all other extensions and ensured chrome web store was not open in a container tab as mentioned in #4 (comment)

Similar problems are observed in Zen Browser version 1.0.2-b.5 and in Floorp Browser version 11.21.0.

However, the manual installation of the extension from the CRX file is successful!

Maybe the extension conversion is not happening, e.g., some MV3 API is missing in Firefox or the add-on is too badly written in Chromium MV2?
